This invention relates to improvements in ,aseptic packs comprisinghypodermic syringe outfits for certain treatments notably for such asusually must of necessity be self administered.

.5 The utility of such packs may be most readily appreciated byconsideration of the circumstances attendant such self treatments andthe essential sterile condition of the instruments which must bemaintained. Those suiering from such diseases as diabetes are dependentupon insulin injections at regular intervals, andwhile the patienteventually acquires a certain degree of skill and care, there is alwayspresent the possibility that some precaution against infection has beenoverlooked.

My invention provides a complete outt including, beside the hypodermicsyringe, a swab and a supply of alcohol, and spare needles coniined inliquid tight compartments in which the sterile condition of theinstruments is ensured. For this outfit I provide a pack which may beconveniently carried as in a pocket without the danger of leakage orbreakage, and which while invaluble to patients and doctors alikebecause of its4 aseptic condition, is also of great use because the packmay beset upright and the instruments contained therein be supported .asby a rack or stand, thus not only facilitating treatments, but alsofurther ensuring the sterility of the instruments.

While I have suggested the use of my invention las practised by thosewho rely on self treatment and who, therefore, may be assumed to have adegree of skill commensurate with their experience, it will be readilyappreciated that my pack will be even more invaluble to those unskilledpersons who will require such treatments in the future and to those whoare clumsy or nervously inclined.

4 In the drawing I have shown and in the specification described asimple embodiment of my invention.

In the drawing:

Fig. 1 is an elevation of my pack.

Fig. 2 is a sectional elevation showing the instruments supported withinthe several tubes, and

Fig. 3 is a View along the lines 3-3 of Fig. 1 showing a slightlymodified form.

My pack consists o1 three tubes l, 2, and 3 which are held in alignmentby the clamp members 4 and 5 which rigidly hold the tubes I and 3. Thetube 2 is provided with an annular recess 6 into which a protuberance 'lon the clamp member 4 ts so that while the tube 2 may be freely rotatedits axial movement is extremely limited.

As shown in Fig. 3 the clamp members 4 and 5 may be detachably united asby the screws 8 to permit the tubes to be used and cleansed` separatelyif desired.

The tube 2 has secured to its lower end as at lI5 3 a resilientsupporting piece ID having flat lateral feet Ita. When my pack is to becarried either by the clip I I or in a leather envelope, the feet IIEaoverlie the ends of the' tubes I and 2 and are held in that position bythe protuberance 1 10 bearing against the lower edge of the annularrecess 6 in the tube 2.

When any of the instruments are to be used, the tube 2 and the feet Illaare pivoted to provide for adequate support so that the pack may 15 beused as a stand. The slight axial movement of the tube 2 frees the feetIlla so that they may lie in the same plane as the bases of the tubes Iand 3.

A hypodermic syringe I2 is suspended in the 20 liquid tight tube 3. Thelinger rest or shoulder I2a of the syringe I2 overlies a rubber washerI3 positioned in the annular recess Ill in the upper end of the tube 3which is enlarged to receive the detachable cap I5. The cap l5 has anin- 25 ternal shoulder I6 which is adapted to bear against the shoulderI2a of the syringe I2 to lock it against its rubber cushion I3. Adetachable bottom 3fL is preferably provided to facilitatesterilization. 30

The tube 2 is also liquid tight and is adapted to conne the spear-headswab Il which is attached to the cap 2a from the tube 2. A gasket I8prevents leakage as this tube is adapted to serve as an alcoholreservoir. The tube I is 35 desired to protect spare needles I9 whichare held in aligned spaced position by the split sleeve 20.

The detachable caps may be secured to their respective tubes in anydesired way, and the support for the tub-es when my pack is to be used40 as a stand may be variously formed, or the pack may be so formed asto permit any one of the tubes, as tube I for the spare needles, to bepivoted to supporting position.

With such an aseptic pack, a patient is able 45.

to carry a complete outfit with him. He needs only to sterilize thecomplete pack and contents by boiling at regular intervals. With such apack, self treatment is made easier for the patient, not only because ofthe ensured sterility, v but also because of the accessibility of theinstruments when supported as in a sterile stand. Various modificationsin the construction and assembly of my device as well as the materialsused may obviously be resorted to without departing from the spirit ofmy invention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. A hypodermic pack unit for pocket or like transportation comprising aplurality of containers, means holding said containers in alignment andpermitting one of said containers to be freely rotated and to haveslight aXial movement, and a support carried by said rotatable containeradapted to lie in alignment with said containers and to be pivoted tosupport said containers in an upright position.

2. A hypodermic pack unit for pocket or like transportation comprising aplurality of containers, members holding said containers in alignmentand permitting one of said containers to be freely rotated and to haveslight axial movement, a support carried by said rotatable containeradapted to lie in alignment with said containers and to be pivoted tosupport said containers in an upright position, one of said containershaving an annular recess and one of said members having a protuberanceadapted to enter said recess, said protuberance and said recess being soshaped as to permit free rotation and limited axial movement of saidcontainer.
